A phase II study on metastatic breast cancer patients treated with weekly vinorelbine with or without trastuzumab according to HER2 expression: changing the natural history of HER2-positive disease.

Purpose: To observe whether in pretreated metastatic breast cancer patients with HER2-positive disease vinorelbine plus trastuzumab can produce different overall response rate (ORR), time to progression (TTP), and overall survival (OS) from women with HER2-negative tumors treated with vinorelbine alone.

Methods: Between June 2000 and January 2004, 68 consecutive women were enrolled: 33 patients received vinorelbine (V) alone, while 35 patients were given trastuzumab plus vinorelbine (T+V) according to HER2 expression determined by immunohistochemistry. In tumors scored +2, HER2 gene amplification was determined by fluorescence in situ hybridization.

Epirubicin plus docetaxel in metastatic breast cancer: escalating dose does not improve efficacy. A phase II study.

Background: The combination of anthracyclines and docetaxel have demonstrated a significant activity in metastatic breast cancer (MBC) as first-line chemotherapy. In a previous multicenter phase I study, we recommended two schedules of epirubicin-docetaxel combination for MBC: 1) epirubicin 75 mg/m2, docetaxel 80 mg/m2 every 3 weeks without G-CSF; 2) epirubicin 90 mg/m2 plus docetaxel 90 mg/m2 every 3 weeks, with G-CSF support.

Patients And Methods: Twenty-five advanced breast cancer patients were treated with epirubicin 90 mg/m2 plus docetaxel 90 mg/m2 every 3 weeks, with prophylactic G-CSF.

Accelerated chemotherapy with high-dose epirubicin and cyclophosphamide plus r-met-HUG-CSF in locally advanced and metastatic breast cancer.

Background: This study evaluated the toxicity of high-dose epirubicin and cyclophosphamide plus r-met-HUG-CSF (G-CSF) given every 2 weeks and compared the dose-intensity achieved with this schedule with that obtained in a previous study we conducted in which the same regimen was given every 3 weeks without G-SCF (EC 21). The secondary objective was to explore the activity of this regimen.

Patients And Methods: Between December 1991 and March 1994, 41 patients (pts), 19 with locally advanced breast cancer (LABC) and 22 with metastatic breast cancer (MBC), were given high-dose epirubicin (Hd-Epi) (120 mg/m2) and cyclophosphamide (CTX) (600 mg/m2) on day 1 every 14 days (EC 14) plus granulocyte colony-stimulating factor (G-CSF) (5 mcg/kg/d s.

Phase II trial of high-dose epirubicin and cyclophosphamide in advanced breast cancer.

Between February 1990 and December 1991 high-dose epirubicin (Epi)(120 mg/m2) plus cyclophosphamide (CTX)(600 mg/m2) were given every 3 weeks to 52 patients with locally advanced and metastatic breast cancer. 26 patients with locally advanced disease received four courses of this regimen before and after local treatments. 26 patients had metastatic disease: they received eight courses unless progression or unacceptable toxicity occurred.
